  • Endodontic tool having reduced torque demands
    Patent number: 7435086
    Abstract: A dental reamer/file is in the form of an elongated shank having a proximal end portion and a distal end and a tapered working portion of determined length extending therebetween, the external surface of the shank working portion having at least two equally spaced apart continuous concave helical flutes and therebetween an equal number of spiraled, spaced apart flanges, each flange having in a plane perpendicular to the length of a longitudinal axis of the shaft an outer end defined by a first and a second surface intersecting at a point of maximum radius from the axis, the first surface being relatively short and the second surface relatively longer, the point of maximum radius providing a spiraled scraping edge.

  • Endodontic file having bi-directional scraping edges
    Patent number: 7300281
    Abstract: An endodontic file having an elongated shank with a proximal end portion, a distal end and a tapered working portion extending from the proximal portion to the distal end, the external surface of the shank working portion being defined in part by a plurality of at least two equally spaced apart continuous helical flutes formed into a central core portion of the shank working portion, the flutes having therebetween an equal number of spiraled spaced apart flanges, each flange having a semi-circular surface having a leading edge and a trailing edge, each edge being in or parallel to a plane of the shank longitudinal axis, each leading and trailing edges providing a cutting or scraping edge.
